DIAGNOSIS

 

The psoriasis diagnosis is based on medical history, (if any family history of psoriasis, current disease activity, the presence of itching, triggering factors, previous treatments), and physical examination that takes into account the appearance of the rash.

 

The diagnosis of psoriasis is based essentially on the features of the clinical picture and the histopathological study (skin biopsy) if there is diagnostic doubt, as there are cases in which there is no family history of the disease and cases where pruritus is absent.

 

The clinical picture is vital if we are in the presence of the characteristic erythematous-squamous lesions with well-defined edges and silvery white scales. When performing the lesions examination, the dermatologist will find the three distinctive signs of psoriasis: the candle wax sign, the pinpoint bleeding sign and the Auspitz’s sign.

 

During the physical examination the doctor should pay special attention to the examination of the scalp, the umbilical region, extensor surfaces of limbs, such as elbows and knees, and the lumbosacral region.

Laboratory tests are not the solution to this problem. Usually you can find negativity for rheumatoid factor, elevated C-reactive protein and erythrocyte sedimentation rate. Further studies can be performed to clarify the cause of possible superinfection of lesions, in particular cultures of microorganisms and fungi.

 

The important thing is to look for other possible triggering factors.  The nasal exudate and the pharyngeal exudate are useful in ruling out infectious foci. Doctors should rule out urinary infections, hepatitis B (Ag) and hepatitis C (Ac) and diseases or comorbidities associated with psoriasis such as diabetes mellitus, hypertension, dyslipidemia, metabolic syndrome and inflammatory bowel disease.

 

It may rarely be necessary to perform a skin biopsy to get a differential diagnosis.

 

Differential diagnosis

• Seborrheic dermatitis (particularly in the case of some lesions on the scalp)

• Chronic eczema

• Nummular eczema

• Atopic dermatitis (in childhood)

• Lichen simplex chronicus

• Pityriasis rosea (particularly for the trunk lesions)

• Pityriasis rubra pilaris (trunk lesion)

• Tinea corporis (trunk lesion)
